The role of Brevipalpus mites as vectors of plant viruses has been known for decades. However, only recentlj their relevance has been acknowledged. The Iist of Brevipalpus-transmitted viruses (BrTV) has increased ir. the last years, reaching close to 50, along with the economic importance 01' the diseases caused by them. The most studied BrTV is the Citrus leprosis vírus C (CiLV-C) due to the losses it causes to the citrus industry in the Americas. Also, Coffee ringspot vírus (CoRSV), Passion fruit green spot vírus (PFGSV), and Orchid fleck viru. (OFV) are of economic importance, wíth the later being the only BrTV with worldwíde distríbutíon probabl. due to the intense intematíonal market of orchids. In the last decade, most of what was accepted about CiLV-C and its interactions with the host and the vector was shown to be inaccurate. Our data bring novel information or its taxonomic classification (originally believed to be a rhabdovirus and now considered the type-member of the recently created Cilevirus), its persistent circulative (and not propagative, as originally proposed) interaction witl B. phoenicis, and the type of response it induces in its host (initially thought to be a HR-type of resistance ane now shown to be typical of compatíble host-virus interaction). |

Drought is a major limitation of maize cultivation in Brazil. Agronomic and physiological practices have been considered to overcome this stress and consequently, increase grain production. The present study investigated the role of abscisic acid (ABA) application in some physiological parameters, in two hybrids with contrasting drought resistance (DKB 390 and BRS 1030 resistant and sensitive, respectively). Contrasting resistance to drought in these genotypes was determined in previous studies. Water deficit was imposed for 10 days at flowering stage, in association with the application of 100lM abscisic acid on plant canopy. Evaluations of gas exchange, chlorophyll fluorescence, relative water content (RWC), and endogenous ABA content were performed during stress period and also at water recovery (recovery irrigation). A significant functional relationship was observed between RWC and the parameters of gas exchange and fluorescence. During water recovery, no differences were observed among the treatments. DKB 390 presented higher photosynthesis rate (Pn) and electron transport rate (ETR) under water stress, while BRS 1030 presented higher intercellular CO2 concentration (Ci) and lower photochemical quenching (qP), non-photochemical quenching (NPQ), and lower Fv/Fm ratio. DBK 390 was more responsive to ABA application than BRS 1030, presenting higher endogenous ABA content in the first day of stress. DBK 390 with ABA application reduced the effect of water stress through maintenance of water status, an increase of photosynthetic parameters, and a decrease of decline in the functions of photosystem II during stress.
